I have a cell array with size (1*100) containing cells that these cells have only numbers 0 and 1. The screenshot of the cell array is attached. Each cell inside the cell array contains a matrix with different sizes. I am not able to convert this cell to matrix because to use cell2mat all cells must be the same size and same class.

My aim is to convert this cell array(1*100) to a matrix.How can I do that?

What size of output are you expecting? Are you trying to convert the various entries into columns of the output? Are you trying to put all of the entries as one continuous column vector?

Hi. Thanks for your reply. I need to try both of the ways you mentioned. I want to get one big vector containing only 1 and zero and then count numbers of zero and 1 for geting true positive and false positive. Also I want to run a loop over the cells and concatenate them one by one to an array. Thanks for your help.
